GGU-ELASTIC: "Align" menu item
You can have the mesh aligned around circles or along lines. First, decide which criterion the program should follow:
"Nodes" button
You can select individual nodes and have them aligned according to your specifications.

Here, you have the option of aligning the selected nodes along an arc, on a horizontal line through y0 or on a vertical line through x0 with the spacing entered in the appropriate input box.
"Line" button
First, click several nodes to be connected by a line and confirm the selection using the [Return] key. You will then see the same dialog box as for "Nodes", only without information on the selected node numbers. After entering and selecting the desired type, the selected nodes will be aligned.
